CVE-2026-72530 is a critical code injection vulnerability in TrueConf Server that allows a remote unauthorized attacker with network access to port 4307/TCP to execute arbitrary code on the host system. The vulnerability affects TrueConf Server versions prior to 5.3, versions from 5.3 up to but not including 5.3.9, versions from 5.4 up to but not including 5.4.9, and versions from 5.5 up to but not including 5.5.5. Exploitation requires a specially crafted script to break out of an isolated environment. The CVSS 4.0 base score is 9.5, indicating critical severity. No patch or remediation information is provided in the input data.

CVE-2026-72529 is a critical vulnerability in TrueConf Server that allows remote attackers with network access to port 4307/TCP to execute arbitrary scripts without authentication. This affects multiple versions of TrueConf Server prior to 5.3, as well as specific ranges within 5.3.x, 5.4.x, and 5.5.x. The flaw stems from missing authentication on a critical function accessible via an undocumented call.

TrueConf Client downloads application update code and applies it without performing verification. An attacker who is able to influence the update delivery path can substitute a tampered update payload. If the payload is executed or installed by the updater, this may result in arbitrary code execution in the context of the updating process or user.
